Before Change

spec = fetch_sdss_spectrum(plate, mjd, fiber)

plt.plot(spec.wavelength(), spec.spectrum, "-k")
plt.xlabel(r"$\lambda (\AA)$")
plt.ylabel("Flux")
plt.title("Plate = %(plate)i, MJD = %(mjd)i, Fiber = %(fiber)i" % locals())
plt.show()

After Change

//------------------------------------------------------------
// Plot the resulting spectrum
ax = plt.axes()
ax.plot(spec.wavelength(), spec.spectrum, "-k", label="spectrum")
ax.plot(spec.wavelength(), spec.error, "-", color="gray", label="error")

ax.legend(loc=4)

ax.set_title("Plate = %(plate)i, MJD = %(mjd)i, Fiber = %(fiber)i" % locals())

ax.text(0.05, 0.95, "z = %.2f" % spec.z, size=16,
